treatment, or impregnating the butt to a greater degree than theremaining portion,

as desired, and one in which either the socalledffull cell, or empty cell process may be carried out.

It is another object to provide an apparatus of the character referred to in which the several parts cooperate to constitute a self-contained compact apparatus highly eflicient in operation and capable of quickly effecting a positive deep penetration within a minimum time, and 1n which the extents of the butts subjected to treatment, when 'such portions are alone impregnated or specially treated, may begoverned to a nicety.

It is a special object to provide an apparatus -l of this kind having a pivotally- 80 mounted treating cylinder which can be easily-.and quickly swung to either a horizontal or vertical position, as desired, and

without in any way disturbin the normal connections to the treating cylinder for de- 5 liveringand exhausting the preservative and the compressed air employed in carrying out the methods of bringing about. the

junction with the following description and the appended claims.

In t part ofthe application, Fig, 1 is a side ele vation of the preferred embodiment of the invention, the treating cylinder being illus trated by full lines in its horizontal position, the position which it assumes when e accompanying drawings, forming swung vertically being indicated in dotted lines; and Fig. 2 a lan view of the a paratus shown in Fig. 1, illustrating t econnections employed for delivering and exhausting the preservative and compressed air to and from the treating cylinder.

Referring to the drawings 1 designates a pit, at the opposite sides of which are located the bearing standards 2, 2 in which are journaled the laterally extending trunnions 3, 3, respectively, the trunnions being anchored to an elongated treating cylinder 4 in any suitable Way. As illustrated, the

trunnions form a part of a sleeve or collar 5 which encircles and-is directly attached to the cylinder 4.

The trunnions 3, 3 are hollow, being bored to provide passageways therethrough as indicated at 6, 6, both trunnions extending beyond the bearing standards, and terminating in one member of a universal joint. The'trunnion' 3 atits terminal carries the socket member 7 of a universal ball and socket joint, while the trunnion 3 terminates in like fashion in the socket memher 7 of a similar ball and socket joint. The. socket members 7, 7' cooperate with the ball members 8, 8, forming. the extremities ofthe conduits 9, 9, respectively, the latter conduit'l'eading from a supply tank 10 for a liquid preservative such as creosote or zinc chloride and is equipped with a suitable cutoff valve 11.

The storage tank 10 as illustrated, is in the form of a so-called weigh tank, equipped with a scale mechanism indicated as a. whole at 12, and corresponds generally in structure and mode of operation to the weigh tank shown and described in my previously granted Patent No. 1,081,158, granted December 9, 1913. Preservative is delivered to the weigh tank through pipe 13 equipped with the control valve 14 from a pressor 20. A pressure of approximately 350 pounds to the square inch is normally maintained in the air compression tank, the air being delivered thereto from the compressor 20, driven by an electric motor 21 posed therein the control valve 23. Leading from the pipe 22, slightly in advance of valve 23, is a branch pipe 241 equipped with the control valves 25 and 26, the free end of this branch pipe communicating with the atmosphere. The conduit 9 leading to the trunnion 3, previously referred to, is

connected with the branch pipe 24 intermediate the valve 25 and the pipe 22, and has interposed. therein the control valve 27. Also leading from the branch pipe 24, at a point intermediate the valves 25 .and 26, is a pipe 28 for delivering compressed air to the upper extremity of, the weigh tank 10, and which has interposed therein the 'control valve 29.

One end of the treating cylinder 4 is closed, while its opposite end, adjacent the trunnions 3, 3, is equipped with an inlet head 30 provided with the inlet opening 31, adapted to be closed by an inwardly opening door 32 pivotally mounted as at 33, and equipped with the counterbalancing device 34.- At an intermediate point, and prefer "-ably at the upper side thereof, the treating cylinder 4 is provided with a plurality of spaced apart petloc'ks, such as indicated at 35, the purpose of which will be subsequent- 1y more fully described.

Communicating with the bore 6 .of the trunnion 3. is a conduit 36' which communicates with the interior of the treating cylinder at a point adjacent its closed end,'the said conduit being carried by and bodily movable with the said cylinder. In a similar fashion, a conduit 37 communicates with the bore of trunnion 3' and enters the interior of the treating cylinder through the bottom of its inlet head, and adjacent its inlet opening, as clearly shown in Fig. 1.

For the purpose of bodil swinging the treating cylinder between a orizontal position, as illustrated by: full lines in Fig. 1, and a vertical position as indicated by the dotted lines in said figure, the trunnion 3' has aflixed thereto the gear 38 which meshes with a pinion 39 carried at the end of a shaft driven by means of the reversible motor 40 through an interposed gear reduction mechanism shown at 41. In order to properly position the treating cylinder when in a horizontal position and to limit its movement, there is provided a supporting abutment 42 upon which the treatingcylinder may rest when in its horizontal position.

The proportions of the several parts'interposed between the motor 40 and the gear 38 are such that the treating cylinder will be positively held, without additional auxiliary locking devices, at any point intermediate its horizontal and vertical positions, and in order to enable the cylinder to be easily swung upon its pivotal mounting, the trunnions 3, 3 are preferably located at a point rendered self-closing, and it is here particularly noted that upon the swinging of the a cylinder from a horizontal to a vertical POSI- tion, the said door is subjected to a gradually incrcasing pressure due to the weight of the preservative and the pole being treated,

located within the interior of the cylinder, tending to enhance the sealing efi'ect preventing egress or escape of the preservative outwardly through the inlet opening 31.

In use, the pole to be treated is inserted through the inlet opening 31 into the interior of the treating cylinder when it occupies a horizontal position. If it be desired to impregnate the entire pole with the preservative, the cylinder. is retained in its horizontal position, While admitting the preservative thereto from the weigh tank 10 through the conduit 9', bore 6' of the trunnion 3, and the conduit 37. If a deep penetration is to be effected, the preservative within the treating cylinder may be subpole to treatment in this manner, .if it is desirable to subject the butt end thereof to an additional treatment to secure a deeper and fuller penetration at this region, it is merely necessary to swing the treating cylinder from a horizontal position to a vertical position, and permit a portion of the preservative to How back'into the weigh tank 10, until the desired level thereof within the treating cylinder is reached. During this step the compressed air previously admitted to the upper portion of the weightank, can be discharged to the atmosphere by way of the pipe 28 and branch pipe 24, the valve 25 being closed and the valves 29 and 26 being opened for this purpose. The level of the preservative within the treating cylinder when in its vertical position can be readily determined by openingthe several pet cocks 35. After the desired level of the reservative has been determined as just escribed, the pet cocks 35 being closed, the preservative retained within the cylinder may be sub'ected to the necessary pressure for securing the desired impregnation by admit I iso . rcoacrr pletion of the impregnating action of the butt, in this manner, the entire quantity of preservative left in the treating cylinder may be discharged backwardly into the weigh tank by opening the valve 11 and adthe cylinder will be first moved to its vertical position, a suliicient' quantity of the preservative then admitted through the conduit 37 from the weigh tank into the cylinder, its level being determined by means of the pet cocks 35, and the remaining steps bein then carried out in a manner similar to that previously described, thus leaving the upper portion of the pole untreated with the preservative.

Due to the ease with which the supplies of preservative and the compressed air, as desired, can be delivered -to and exhausted from the treating cylinder, by properly manipulating the several control valves provided, the apparatus readily lends itself to the carrying out of either the full cell or empty cell process well known to this art.

During the swinging of the treating cylvinder between the limits defined by its horizontal and vertical positions, the several conduits 36 and 37 move bodily with the cylinder, but without in any way aifectin the delivery or exhaust of the treating fliiids, due to the provision of'the universal connections located at the extremities of the trunnions 3, 3'.

It is thus seen that the invention provides a very simple, convenient, compact, .and efs, ficient apparatusfor treating either the entire pole or merely the butts thereof, one by which a positive deep penetration with the preservative may be accomplished in a mini-.

mum period of time, one in which the bodily swinging of the treating cylinder does not disturb the normal connections for delivering and exhausting the fluids employed, and one which is automatically self-sealing against the accidental escape of the preservative'from the cylinder when it is swung to its vertical position.
